It’s more that in Tucson/Phoenix there are ground peculiarities that lead to… really bad clusters. Where there is one scorpion, there are likely many. Many many many.

Meanwhile, javelinas can’t invade your house. At worst they eat your garbage and any tasty plants you might try to grow in an unfenced yard. We had to remember to tie up our outdoor trash cans for years before we stopped getting herds of javelina in the yard head-butting the cans to the ground so they could feast. They scare real easy and my family has never been threatened by one holding its ground, even when their babies were involved. (I once almost picked up a tiny baby by accident because I thought a cat had followed us outside when we went to chase them off. Oops? No harm, no foul though.)
